Given a force of 56 n and an acceleration of 7 m\s2, what is the mass

56 n/ 7 m/s^2 = 8kg

Example:
To solve this given word problem we can first identify the given and the apt formula to use in this phenomenon: Given: Force = 4, 500 N = 4, 500 kg-m/s^2 Acceleration = 5 m/s^2   
Formula: f=ma 
Derivation: m = f/a 
Solution: 
1.    M = f/a 
2.    M = 4,500 kg-m/s^2 / 5 m/s^2 
3.    M = 900 kg   

Hence, the object’s mass is 900 kg.
